The Hard disk must have 3.5" form factor to fit, possibly a Miniscribe
or similar. There are two possibilities :
(1) Remove 2nd floppy, then put in the harddisk instead.
    Not recommended if you're used to having two floppy disk drives.
(2) Placing the HD between power supply and bus card. (The buscard is the
    one which stands up. It also contains a battery for the real time clock.)
    There is enough space to fit a Miniscribe (e.g.) with ca. 10 mm left
    on each side. The problem is to mount the disk securely. The best way seems
    to be to put two strips of metal on top, screw the Hard disk to that
    and then put it inside the computer that way, with the HD hanging down
    from the strips and the strips being supported on the left and right
    by the power supply and the bus card.
Controller: You can user almost any XT-controller. I recommend OMTI, Adaptec
    or WD. It is possible to use a RLL-controller! The adress would be C800: ,
    just like in a regular XT.

Before you try this with ANY drive, check it's manual first, most of the
hard disks I have seen will NOT permit this orientation (Upside down).

Don't ask ME why not, I can only guess, but I'm sure they have a good
reason for it.
